# CDR016 - Serving SID assigned to serving cellsite not found

Override is allowed

| Name | Serving SID assigned to serving cellsite not found. |
| --- | --- |
| Common Cause | The serving cellsite in this usage record is not configured in the Cellsite table correctly. |
| Common Resolution(s) | Actions you can take to resolve the problem: - The Cellsite table is improperly configured. Find the ***InitialCellsiteID*** column in the SPUN record (the ***ALL COLUMNS*** view option must be chosen); this is the CellSiteID in the Cellsites table. Use Admin Console ‘Cellsites’ to edit this entry in the cellsite table – specify a good Serving SID. - The SID table may be out-of-date. Contact IDI BCT to upload any newer version of this table. - If the usage record should be billed anyway, choose Override Rule on the usage record. If this is done frequently, consider a change to Unbillable Rules for this Unbillable Code. Note that ignoring lookup failures can have undesirable downstream repercussions including rating and discounting failures and poor invoice presentation. |
| Details | Each cellsite in the Cellsite table must specify its Serving SID, which is vital to downstream processing. In this case, the cellsite in the cellsite table did not contain a Serving SID or contained a Serving SID which was not in the SID table. |
